I gotta say this is proving quite successful!
I've been experiementing with using NLP in my facebook chats with girls and i am definatly getting more and better quality responses.
In one case i messaged a girl i havent seen or spoken to in years, and inside 30 minutes she had given me her mobile number (without me asking) and asking to spend a weekend with me
The experiment continues....
I'm not sure how i could get it into my everyday conversations though, with messaging and online stuff you have the time to think and rewrite for the best effect, but with conversations you need to already be thinking this stuff on the fly which is one step beyond for me.
